颊脂垫瓣移转在腭裂修复中的应用

目的介绍颊脂垫瓣移转的应用原理及用以腭裂修复的实践。方法将颊脂垫瓣移植于硬腭裂隙的口腔侧创面，或充填于腭部的口腔与鼻腔侧组织瓣之间，尤其是硬软腭交界处。颊脂垫不需用皮片覆盖，可以自行上皮化。结果共治疗腭裂６例，术后颊脂垫完全成活，无腭瘘形成，无颊间隙感染发生。２周后，颊脂垫自行上皮化。结论颊脂垫血供丰富，易于成活，可为Ⅱ期愈合的创面提供肉芽组织再生床，改善软硬组织血供，以促进伤口的愈合。使通过常规的手术方法不能或难以修复的大的裂隙或缺损得以修复

The application of the pedicled buccal fat pad graft in cleft palate repair

Objective\ The purpose of this paper is to provide the experience in using the pedicled buccal fat pad (BFP) graft in cleft palate repair when healing by secondary intention may need to be considered due to the width of the cleft;the qualitative or quantitative tissue constraints,the dead cavity between the oral and nasal layers or single layer closure of the hard palate with the vomer and marginal pedicled mucosoperiosteal flap.Methods\ The body and buccal extension of BFP is gently torn out from its bed and advanced into the palate vault around the posterior aspect of the maxilla to cover the raw surface of the hard palate cleft and /or fill the dead cavity between the oral and nasal tissue layers,specifically in the conjunction of the hard and soft palate.Results\ Six cleft palates were repaired with the BFP graft.The postoperative course was uneventful.The BFP graft is viable without the occurrence of fistula or infection. Conclusion\ The pedicled BFP graft has provided an excellent soft tissue support for secondary epithelialization when primary dehiscence has or would have otherwise thwarted ultimate closure of the palatal defect.The pedicled BFP graft permits closure of palatal defects that could not be repaired by conventional procedures.
